Setting Option Bytes in Firmware with Secure Manager

[Shizu_T]

Hello,

I am implementing Secure Manager V1.2.0 from X-CUBE-SEC-M-H5 in my firmware. I am following the instructions provided in the "How to start with Secure Manager (customized configuration) on STM32H5" page.

Is it possible to configure Option Bytes outside of the specific registers described on that page?

To clarify, I am developing firmware for the STM32H573VI and plan to incorporate Secure Manager V1.2.0. My non-secure application requires High-Cycle Data, which can be set through the EDATA1R_PRG register.

Hello @Shizu_T ,

I believe this is a mistake in the wiki article. The EDATAxR_PRG should be configurable using the TPC tool. 

The note regarding ignored settings is only valid for the security settings used to support the Secure Manager.

I'll check the actual state ASAP and request update of the Wiki.

Thanks for reporting us the problem.

BR,
